The plugin check site reads the plugin version numbers supplied by Firefox and compares them with version numbers supplied by the plugin vendors.

It sounds like there is a mismatch in this case:

• Firefox is reporting a number like "15.8.20082" ??
• The site is checking for "2015.008.20082"

To confirm that first point about what Firefox exposes to websites, could you visit this test page and look at the blue number in parentheses and let me know what you see: https://jeffersonscher.com/res/plugins.html

Jeff, Thanks for the quick response. This is what I see for Adobe Acrobat DC Name (Version): Adobe Acrobat (15.8.20082.15957) Rita To confirm that first point about what Firefox exposes to websites, could you visit this test page and look at the blue number in parentheses and let me know what you see: https://jeffersonscher.com/res/plugins.html

Jeff: I imbedded my response in your response. Here's a clearer response. This is what I see when I open your URL for Adobe Acrobat

Name (Version): Adobe Acrobat (15.8.20082.15957)

I think it's a "bug" in the data used by the plugin checker.

I recommend checking for Adobe Reader updates from inside the product, using Help > Check for Updates, and trusting Adobe to update both the main product and plugins together.
